The main bridge of Chaoyang bridge is totally 1208m long. This paper summarizes the new materials, new workmanships, new techniques, engineering characteristics and key techniques designed for the bridge. In view of and for better use of the wide Ganjiang River waters, including the test track and planned main channel, the main bridge is arranged to be a six-pylon cable-stayed bridge with spans of (79+5×150+79) m. The main girder is a corrugated steel web-PC composite beam. The pylons adopt the “diamond-shaped” model and the spacing of the stay cables is 6. 5 m to optimize the architectural modeling, material consumption and mechanical performance. The main girder is fixed with the pylon and separated from the pier, and the ratio of the side span and central span is 0. 53 that guarantees the best structural performance of the whole bridge.
